The Bihar Vigilance Bureau interrogating former Patna district magistrate Gautam Goswami, the key accused in a multi-crore flood relief scam, is likely to seek an extension of his remand from the designated vigilance court as he has not revealed any important information so far.

"The bureau will soon file a plea in the court seeking extension of his remand," a top official of the bureau said.

He said during his interrogation, Goswami either remained silent for most of the time or denied his involvement in the embezzlement of flood relief funds stating that he had conducted the relief operations as per the directives of the top officials of the state administration.

"Gautam's behaviour during interrogation is a deliberate move to pass time in police remand without revealing anything. But it is going to be tough for him if the remand is extended," the official pointed out.
